IF THE ENGINE OVERHEATS  
If your temperature gauge indicates  
overheating, you experience a loss of  
power, or hear loud pinging or knocking,  
the engine may be overheating. If this  
happens, you should:  
4. Check for coolant leaking from the  
radiator, hoses or under the vehicle. (If  
the air conditioning had been in use, it  
is normal for cold water to be draining  
from it when you stop.)  
1. Pull off the road and stop as soon as it  
is safe to do so.  
2. Shift the gear to P (Park) and set the  
parking brake. If the air conditioning is  
ON, turn it OFF.  
5. If engine coolant is leaking out, stop  
the engine immediately and call the  
nearest authorized HYUNDAI dealer  
for assistance.  
3. If engine coolant is running out under  
the vehicle or steam is coming out  
from the hood, stop the engine. Do  
not open the hood until the coolant  
has stopped running or the steaming  
has stopped. If there is no visible  
loss of engine coolant and no steam,  
leave the engine running and check  
to be sure the engine cooling fan is  
operating. If the fan is not running,  
turn the engine off.  
WARNING  
Never remove the engine  
coolant cap and/or water-  
cooled intercooler coolant  
cap or the drain plug while the  
engine and radiator are hot.  
Hot coolant and steam may blow out  
under pressure, causing serious injury.  
Turn the engine off and wait until the  
engine cools down. Use extreme care  
when removing the coolant cap. Wrap  
a thick towel around it, and turn it  
counterclockwise slowly to the first  
stop. Step back while the pressure is  
released from the cooling system. When  
you are sure all the pressure has been  
released, press down on the cap, using  
a thick towel, and continue turning  
counterclockwise to remove it.  
WARNING  
While the engine is running,  
keep hands, clothing and tools  
away from the moving parts  
such as the cooling fan and  
drive belt to prevent serious  
injury.

Emergency situations  
6. If you cannot find the cause of the  
overheating, wait until the engine  
temperature has returned to normal.  
Then, if coolant has been lost,  
CAUTION  
śꢀ Serious loss of coolant indicates  
a leak in the cooling system and  
have the system be checked by an  
authorized HYUNDAI dealer.  
carefully add coolant to the reservoir  
to bring the fluid level in the reservoir  
up to the halfway mark.  
śꢀ When the engine overheats from  
low engine coolant, suddenly adding  
engine coolant may cause cracks  
in the engine. To prevent damage,  
add engine coolant slowly in small  
quantities. It may require several  
refilling cycles to properly fill the  
engine cooling system. If necessary,  
an authorized HYUNDAI dealer  
should be consulted to perform this  
task.  
7. Proceed with caution, keeping alert  
for further signs of overheating. If  
overheating happens again, call  
an authorized HYUNDAI dealer for  
assistance.
